Ya, it's probably a better idea anyway rather than modifying a perfectly good compressor that I would have to drive 5 hours to get out of storage.  :~)

Well I went up to the dump and found a couple of fridge compressors.  I took one out of a 2003 fridge but it is small so I also took one out of an older fridge because is was big and had larger lines.  I'm assuming that the big one will work better if it works at all.
Anyway, I tried them both and couldn't get a response out of either of them so just want to be clear on what I'm doing.  
#1 (the newer one) has three wires coming out of the plastic box.  A red (power), a white (neutral) and a green (grd).  Hook 'em up and nothing.  
#2 (the older one) has three wires.  Two come out of the bottom of the box and there are two little round thingamajigs inside the box.  Two of the wires (brown and white) come from the bottom thingamajig and one wire (yellow with a brown spiral line) comes from the other thingamajig which is wired to the first thingamajig.
As you can tell from the highly technical style of writing I employ, I am not an electrician.  I do however, have a fair bit of experience with household wiring and automotive wiring but know nothing of how these compressors work.  
Any advice would surely be appreciated.

Thanks for the links.  Wouldn't you know it, I had to pick two non-working compressors.

Another thought on the idea of the vacuum tank.  I haven't gotten around to actually putting vacuum to my tank yet but my tank is almost ready for a vac pump.  
I just wondered, has anyone tried teeing a line off the vac pump at the engine to charge a vac tank?  Would the vac pump on a 6.5TD make enough vacuum to suck oil into a 30 gal tank in a reasonable amount of time?
Edit:  The vac pump on a 6.5TD pulls 30" of vac.

Yes, using the vacuum produced by the on board vacuum pump works.
Always make sure that you close the line between the pump and the tank before drawing WVO though. Otherwise it is possible to draw wvo into the vacuum  pump and harm it. Unlikely..but possible.

Thanks Dana:  Yeah, I am thinking about putting it on a switched solenoid.  I've been discussing the merits of switching to a mechanical wastegate controller on the dieselplace forum.  
I'll start by borrowing vacuum from it (without the solenoid) first though and see how slow/quick it is.

Tks
